Water heating unit is connected by pipe valve unit；Water, to water heating unit heats to 85 degree, is beaten through inlet pipeline by water pump
The high temperature heat-exchanging loop for entering oil water heat exchange unit exchanges heat with the low-temperature oil in low-temperature heat exchange circuit, make 20 degree or so of low-temperature oil from
Low-temperature oil input port enters oil water heat exchange unit, by low-temperature oil from 20 degree or so heat exchange to 60 degree of left sides after oil water heat exchange unit
The right side, from heat exchange oil outlet output；To 85 degree, 85 degree of high-temperature water enters grease through outlet pipeline and changes water heating unit heats water
After hot cell, after exchanging heat with 20 degree or so low-temperature oils, water temperature is lower by height and squeezes into water heating unit heats through water-supply valve again
Circulation is formed, the transformer oil of heat exchange oil outlet output steady temperature is to transformer.
The water heating unit or electric-heating water or heated by natural gas water.
Water position manages filter on the inlet pipeline or outlet pipeline.
Water position reason filter, water compensating valve and water tank, water treatment filter on the inlet pipeline or outlet pipeline
It can separate with water compensating valve and water tank in inlet pipeline or outlet pipeline.
The invention has the advantages that principle is to be added to water using Water electric heater by electricity-water-oil indirect heating method
Suitable temperature recycles oil water heat exchange device to heat oil, and since heat exchanger thermal loss is low, insulating oil can be fast by safety
Speed is heated to required temperature.Injury caused by directly heating to oil is not only avoided in this way, but also improves efficiency.
